Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) =
=
= 0.0316
For x = 120, sample proportion(p) =
=
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z <
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Answer:
While selecting the access control system (software or hardware), there are many factors that influence it and those factors are campus location, network capabilities, number of users using it, size of campus, the motive for using it, etc.

Your Windows 7 client systems are joined to the WestSim.com domain. To ensure correct time stamps are used, you need to verify that these clients are configured for the appropriate time zone.
Which command can you use to do this?
• w32tm /tz
• w32tm /monitor
• w32tm /register
• w32tm /query /status
<u>Answer:</u>
w32tm /tz
command can you use to do this
<u>Explanation:</u>
W32tm.exe is the approved command-line mechanism for configuring, monitoring, or troubleshooting the Windows Time service. This mechanism is a portion of the default connection between Windows and Windows Server. One can use W32tm.exe to configure Windows Time service settings and to diagnose time setting obstacles.
The syntax is W32tm </parameter> </param2>. w32tm /tz will represent contemporary time zone settings. The Windows Time service is not a full-featured NTP clarification that convenes time-sensitive reinforcement requirements, and it is not verified by Microsoft as such.
